HESI LPN ENTRANCE EXAM PREP COMPLETE 300+ PRACTICE QUESTIONS WITH 100% VERIFIED ANSWERS & DETAILED RATIONALES | COMPLETE NURSING SCHOOL ADMISSION TEST STUDY GUIDE (MATH, READING, VOCABULARY, GRAMMAR, BIOLOGY & ANATOMY) 1. A patient's blood pressure is 140/90 mm Hg. What is the pulse pressure? A) 30 mm Hg B) 50 mm Hg C) 90 mm Hg D) 140 mm Hg Correct Answer: B) 50 mm Hg *Rationale: Pulse pressure = systolic minus diastolic = 140 – 90 = 50 mm Hg. It reflects the force the heart generates with each contraction.* ________________________________________ 2. Which sentence is grammatically correct? A) The nurse gave the medication to the patient and I. B) Between you and me, the patient seems anxious. C) Each of the students have their own stethoscope. D) The doctor recommended that the patient rests more. Correct Answer: B) Between you and me, the patient seems anxious. Rationale: "Between you and me" is correct because prepositions like "between" require object pronouns (me, him, her, us, them). "I" is a subject pronoun; "have" should be "has" with "each"; "rests" should be "rest" in the subjunctive. ________________________________________ 3. A cell that secretes antibodies is called a _____. A) plasma cell B) memory T cell C) natural killer cell D) macrophage Correct Answer: A) plasma cell Rationale: Plasma cells are differentiated B lymphocytes that produce and secrete large quantities of antibodies. Memory T cells are for long-term immunity; NK cells kill virally infected cells; macrophages phagocytose pathogens. ________________________________________ 4. Solve: 15 + (6 × 4) – 10 ÷ 2 A) 29 B) 32 C) 34 D) 37 Correct Answer: A) 29 *Rationale: Order of operations (PEMDAS): 6×4=24, 10÷2=5, then 15+24=39, minus 5 = 29.* ________________________________________ 5. The word "alleviate" most nearly means: A) worsen B) intensify C) relieve D) ignore Correct Answer: C) relieve Rationale: Alleviate means to make less severe, e.g., "medication alleviates pain." Worsen and intensify are antonyms; ignore is unrelated. ________________________________________ 6. Which organelle is responsible for ATP production? A) Ribosome B) Nucleus C) Mitochondrion D) Golgi apparatus Correct Answer: C) Mitochondrion Rationale: Mitochondria generate ATP via cellular respiration. Ribosomes make proteins; nucleus houses DNA; Golgi modifies and packages proteins. ________________________________________ 7. If a nurse mixes 300 mL of a 10% dextrose solution with 200 mL of a 5% dextrose solution, what is the final concentration? A) 6% B) 7% C) 8% D) 9% Correct Answer: C) 8% *Rationale: Total dextrose = (300×0.10) + (200×0.05) = 30 + 10 = 40 g. Total volume = 500 mL. Concentration = 40/500 = 0.08 = 8%.* ________________________________________ 8. Read the passage: "The nurse observed the patient's gait was unsteady and her speech was slurred. These findings were noted after the patient fell." The word "gait" means: A) mood B) posture C) manner of walking D) breathing pattern Correct Answer: C) manner of walking Rationale: In medical context, gait refers to the pattern of walking. Slurred speech + unsteady gait are classic neurological findings. ________________________________________ 9. Which of the following is an example of a positive feedback loop in the body? A) Regulation of blood glucose by insulin B) Maintenance of body temperature C) Blood clotting after injury D) Blood pressure regulation Correct Answer: C) Blood clotting after injury Rationale: Positive feedback amplifies a change. Clotting: platelets attract more platelets, enhancing the response until clot forms. A, B, D are negative feedback (reduce deviation). ________________________________________
